Ethan says that the value of 40.7 is 10 times the value of 40.7 is be correct?

No.

Step-by-step explanation:

40.7 times 10 would be 407, not 40.7 ; 40.7 times 1 is 40.7

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
